Maintenance Tips

• Use a Lithium-Compatible Charger – Ensure that you're using a LiFePO4-specific charger. Standard lead-acid chargers can damage the battery and reduce its lifespan.
• Maintain Voltage Levels – Keep the battery’s charge between 20% and 100%. Avoid letting the charge fall below 10V to prevent damage and maximize battery life.
• Keep Temperature in Check – LiFePO4 batteries perform best in temperatures between -4°F to 140°F. For charging, ensure the battery temperature is above 32°F.
• Ensure Secure Installation – Properly mount the battery to prevent movement or vibrations that could cause internal damage or decrease performance over time.
• Inspect Terminals and Clean Regularly – Check terminals for corrosion and ensure they are tightly connected. Use dielectric grease to prevent oxidation and maintain a solid connection.
• Store with Care – If storing the battery for a while, keep it at 50-80% charge and in a cool, dry place. Disconnect it to avoid parasitic drain when not in use.
• Avoid Jump-Starting with Lead-Acid Batteries – Jump-starting from traditional lead-acid batteries can cause voltage spikes that may damage your Battery Management System (BMS).
• Monitor Battery Management System (BMS) – The BMS ensures safe operation by preventing overcharging, deep discharges, and overheating. If the BMS shuts down the battery, allow it to reset before recharging.
• Prevent Deep Discharges – While LiFePO4 batteries handle deep cycles better than lead-acid, regular discharges below 20% can shorten their lifespan. Keep the charge in the recommended range.
• Follow Manufacturer Instructions – Always adhere to PowerTex’s maintenance recommendations for the best performance and to maximize the lifespan of your battery.
